Looking for better design information than is contained in IPC 7525A. Specifically the minimum trough width and length of the step to achieve the necessary paste reduction.

I have that article. While some of the information is helpful, there is no direction as to the length and width of the step to achieve blade deflection to reduce paste.

Would be nice to see your profile, as I would imagine you could be too cool in reflow especially if seeing milky residues in Paste could be Organics that havent volatised out properly

Hi All, I need to know all about intrusive soldering. A site with all possible details about stencil design, paste printing for intrusive soldering and etc.. would be very helpful to me. Thanking you in advance,

You don't say how many headers you have to solder. I usually spec in High temp headers and use a pin-in-paste methodology and double reflow. Can you get your headers high temperature?

can we use same reflow oven for lead free and leaded solder paste, is there any chance of lead contamination in lead-free products.

Hi guys, we have a problem and I hope something can give nme some new information. We have big solderability problems with a gold plated board. We changed the paste already, but there is no improvement. Could the Vapor phase Technology cause the p

Have you re-visited your paste manufacturers profile requirements? Start there, adjust accordingly to critical components on the boards (ie LED's, moisture sensitive, etc..).

Your most likely ramping temp to fast and boiling the flux, or do have moisture in the fabs. BTW every solder paste rep has the solution until their product doesn.t work then they have excuses.

Sorry, I guess I don't know how to address an individual on this thread directly. The fella who represents the anti-flux solder paste - Graham Cooper.
